here this fall.
  
I just went through this exact decision making process and I believe the
GNS480 will survive because there is a significant camp that loves the
480 and hates the 530....and vise versa and Garmin recognizes this.  I
am making the Chelton my primary GPS and am planning on it to have gamma
3 capability this fall.  For me, I decided to not have a (W) receiver as
back up.  The thought being, if WAAS goes out, the non WAAS receiver
would not loose capability and could still go point to point.
